ROLLER Fousl FELTING HAT-BODIES.

SPECIFICATION forming part of Letters Patent No. 284,411, dated September 4, 18873.

Application filed` June 21, isea. (No model.)

ToaZZ whom it may concern Be it known that I, CARLOS W. GLOVER, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and `useful Improvements in Rollers for Felting Hat-Bodies, of which the following is a full, clear, and exact description.

This invention relates to the construction of lags of rollers used in a machine for felting or sizing hats or other articles, such a machine being shown in an application for Letters Patent of theUnited States, iiledby meintheUnited States Patent Ofiice, December 19, 1882; and it consists in a peculiar construction and shape of the lags in cross-`section for rollers of such machines, substantially as hereinafter fully described, reference being had to theaccompanying plate of drawings, in which- Figure 1 is a side view of a felting-roller `having lags arranged longitudinally thereon,

and constructed inV cross-section according to this invention. of Fig. 1. Figs. 3, 4, 5, 6, 7,18,'9, and 10 represent, respectively, lags in cross-section constructed according to this invention, and as attached to a roller in detail.

In the drawings, A represents a roller for use in a machine for felting or sizing hats, Src.,

. such as shown in my said application, except as to this invention, and havinga j ournal,` a,

at each end, by and on which it is supported and rotates in said machine.

b b are lags on the outer surface of the roller VA, .extending longitudinally in a line parallel to its axis, and secured in any suitable manner to the roller. These lags b have a shape or outline in cross-section for the purposes of this invention, as will now be described. In Figs. 1, 2, and 3 each lag b has its sides ff and upper or outer surface, y, concave, forming bej tween the concave sides ff and the surface` g edges h, which, in relation to the sides and upper-surface, are prominent and projecting.

#In Fig. 4L the sides j' f areconcave and the upper and outer surface, g, flat or straight,.leav

ing the prominent and projecting edges h, as in Figs. 1,12, and 8, while in Fig. 5 the upper and outer surface, y, is concave and the sides f f flat or straight, leaving the prominent and proj ecting edges h. In Fig. 6 the sides ff and upper or outer surface, g, are concave; but the `or projecting.

Fig. 2 is a transverse section concavity of each side `runs in two straight lines, l and m, inclining inward, asA shown, leaving the prominent and projecting edges h. In Fig. 7 the sides ff and upper or outer surface, g, are concave. I he edges h are rounded, as Shown, but prominent and projecting. In Fig. 8 the sides ff and upper or outer'surface, g, are concave. The edges haresquare, as shown, but prominent and projecting. In Fig. 9 the sides f f are concave; but the line of yeach side inclines inward and extends to the surface of the roller, the upper or outer surface, g, being flat or straight, leaving the edges h prominent Fig. 10 has similar concave sides f f to those shown in Fig. 9 5 but the upper or outer surface, y, is concave, which leaves the edgesh prominent and projecting. These lags, as described and shown, are all shaped in cross-section so that an edge or edges, h, are formed on the outer or working portionrrof the outersurface of the lags are prominent and proj ecting,and rollers having lags ofthe coni struction herein described and shown, when used in a machine to felt and size hats, &c. ,will bear in a positive'manner, Vby reason of such prominent and projecting edges, upon or press or take hold of the hat-roll, so that the Same will be surely turned and'rolled in the machine, and the felting or sizing of the hat, Src., the quicker, better, and more certainly accomplished than with rollers having lags constructed as at present and heretofore.

The lags, in lieu of extending the length of the roller in one piece, can be in sections, and can run in a, line parallel withor at an angle to the axis, or,spirally around the roller, or in any suitable manner, this invention not being limited to the arrangement of the lags upon the roller; also, these lags can be arranged upon aat surface or uponbelts, or on the interior surface of the drum, or in any suitable manner for operation upon the hat-roll, &c.,

and the lags canbe made of metal or wood, or of any suitable material. They can be constructed IOO l. A roller for felting hats or other articles, having a lag or lags with a concave side, substantially as and for the purpose specified.

2. A roller for felting hats or other articles,

5 having. a lag or lags with concave sides f f, substantially as and for the purpose specified.

3. A roller for felting hats or other articles, having a lag or lags with aconcave upper or outer surface, g, substantially as and for the.

1o purpose specified.

4. A roller for felting hats or other articles,

having a lag or lags with concave sides ff and concave upper surface, g, substantially as and for the purpose specifiech In testimony whereof I have hereunto set my I 5 hand in the presence of two subscribing Witnesses.
